We tested the impact of spatial bias by examining global trends in MHW proxies derived from HadSST3 data.

However, the Hadley Centre SST data set60, 61 (HadSST3, v3.1.1.0) is not global in coverage: rather than interpolating over all space and time coordinates it consists of spatial means within 5 ° × 5 ° bins, leading to missing values in the absence of data.

It has been shown, by sampling globally complete data with realistic temporal and spatial variability, that this extrapolation procedure yields a more accurate estimate of annual global temperature than global integration methods that restrict the area to regions very close to observed points.

Tide gauges have the following disadvantages for determining global sea level changes: uneven distribution around the world; missing data; spatial and temporal variations in ocean circulations; and land movements.
